Applicant's summary and conclusion
- Conclusions:
- The physical state of arsenic acid is described both as a liquid and as a solid crystalline.
- Executive summary:
The physical state of arsenic acid was found to be liquid (arsenic acid solution) and to be solid (arsenic acid hemihydrate).
The reliability of this result has been considered as 2 (reliable with restrictions) because 'CRC Handbook of Chemistry and Physics' is cited as a reference book containing peer reviewed data in the REACH Guidance Document R.7a.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
